[PATCH v7 0/3] add new ima hook ima_kexec_cmdline to measure kexec boot cmdline args

2019-06-06 Thread Prakhar Srivastava
The motive behind the patch series is to measure the boot cmdline args used for soft reboot/kexec case. For secure boot attestation, it is necessary to measure the kernel command line and the kernel version. For cold boot, the boot loader can be enhanced to measure these parameters.

[PATCH v7 2/3] add a new ima template field buf

2019-06-06 Thread Prakhar Srivastava
A buffer(kexec cmdline args) measured into ima cannot be appraised without already being aware of the buffer contents. Since hashes are non-reversible, raw buffer is needed for validation or regenerating hash for appraisal/attestation. This patch adds support to ima to allow store/read the buffer

[PATCH v7 1/3] Add a new ima hook ima_kexec_cmdline to measure cmdline args

2019-06-06 Thread Prakhar Srivastava
This patch adds support in ima to measure kexec cmdline args during soft reboot kexec_file_load. - A new ima hook ima_kexec_cmdline is defined to be called by the kexec code. - A new function process_buffer_measurement is defined to measure the buffer hash into the ima log. - A new func policy

[PATCH v7 3/3] call ima_kexec_cmdline to measure the cmdline args
